Gregory L. Blackstock (American, b. 1946) More Colorful Egg Pattern Favorites to Go For, 2005 For Seattle artist Gregory L. Blackstock, who is autistic, the world is made up of countless things needing to be identified, ordered, and arranged—be they turkeys or cougars, flags or fireworks. Creating art has become his outlet for defining an unpredictable world. Once he chooses a subject, he seeks to record all the variations within that group, to make the artwork “complete.” This process yields intricately tiled and labeled freehand drawings that span multiple pieces of paper added with tape and glue. Presented here for this 1,000-piece puzzle are designs Blackstock researched from various countries’ flags, along with such familiar patterns as plaid, checkerboard, and brickwall.
